How To Use Applied Ballistic for Precision Rifle 

Here are some numbers from one of my 6.5s on Applied Ballistics: Correct site height of 2.5: 700 yards, 0 degree shot angle: drop is 16.5 MOA 700 yards, 30 degree shot angle: drop is 13.8 MOA Default site height of 1.5: 700 yards, 0 degree shot angle is 17.4 MOA 700 yards, 30 degree shot angle is 14.6 MOA. So by not inputting correct SH, data corrections are off .75 MOA on level or 1 MOA on angled shots. My interpretation is that Clay's intention was to convey that sight height is important. Not necessarily more important on angle shots.

I can't show the math here, but the concept of it isn't too difficult. If you could somehow have your scope look directly down the bore of the barrel, the bullet would impact low depending on the distance. As soon as the projectile leaves the barrel gravity works and it begins to fall. Shoot a gun flat, and drop a book from the same height; The bullet and book hit the ground at the same time. However, with scopes being above the axis of the barrel, the projectile will cross the plane of the scope twice; once on the way up and once on the way down. This is why the popular 50/200 zero is possible. Generally, the lower the scope height the longer the Maximum Point Blank Range if all else is equal.
